Detecting doctored photos

This PBS site provides a 13-minute video on a Dartmouth professor, Hany Farid, who is developing news ways to help people detect photos that have been manipulated. After watching the video, the site then invites viewers to examine 9 photos to try to determine whether they are real or fake. After making your choice, an audio clip of Professor Farid explains why you were right or wrong. This is a useful tool for anyone teaching photojournalism and the hazards of photo manipulation.
